The boring storage
company is having
its biggest year yet.
AI doesn't run on hard drives — but it *trains* on them. The math changed.

✦ The bottom line
Q3 revenue: $3.11B — up from $2.16B a year ago. Nine months in, Seagate has booked $8.57B, up from $6.65B. The pattern is consistent, not a one-quarter spike.

Money coming in
Every dollar customers paid Seagate — for hard drives sold to (Amazon, Microsoft, Google), enterprise data-center operators, and consumer electronics.
The huge AI workloads run on flash and , but the training data and backup data sit on hard drives. That's where Seagate plays.
Wall Street calls this
Revenue / Net revenue
+44% revenue growth at a 45-year-old hardware company isn't normal. It signals the demand backdrop shifted — *not just one customer order.*
Q3 revenue · the latest quarter
$3.11
B
Up 44% from $2.16B a year earlier. Beat the high end of Seagate's own guidance. Q4 already guided to $3.45B, roughly +50% YoY.
A single 44% quarter could be a blip: pulled-forward orders, a one-time deal, an easy base. The honest check is to zoom out — does the quarter-on-quarter pattern hold? Looking at the full nine months of fiscal 2026 versus the same nine months last year gives a cleaner read.
Revenue · 9 months
$8.57
B
Up from $6.65B in the prior-year period — +29% across three full quarters. The full-year run-rate is the highest since 2018.
+44% in one quarter, +29% across nine months — Seagate is clearly growing again. But every hard-drive maker is reading the same AI-storage tailwind. To tell whether Seagate is winning the cycle or just floating with it, compare it head-to-head against its only US-listed pure HDD peer. Both companies sell into the same hyperscalers from very similar product lines.
The two US-listed pure HDD makers are growing almost identically — the cycle, not the company, is doing the work. The real differentiation is how they're using the cash that growth produces.
